Lincoln Recalls 11,623 Nautilus, Corsair Hybrids That Can Slip Into Neutral While Driving
A supplier's unapproved anti-rust oil can corrode the hybrid SUVs' park module. Dealers will replace it, but Ford hasn't said when parts will arrive.
Ford is recalling 11,623 Lincoln Nautilus Hybrid and Corsair Hybrid SUVs in the U.S. because a corroding transmission module can drop them into Neutral while they're moving, cutting drive power without warning. Dealers will swap the part for free, but Ford hasn't said when replacement modules will reach them.
Nearly all of the affected vehicles are 2026–2027 Nautilus Hybrids: 11,560 built between September 9, 2025, and August 6, 2026. The other 63 are 2027 Corsair Hybrids built from March 12 to July 8, 2026, early examples of the refreshed, hybrid-only Corsair that now starts at $48,790. Ford estimates every vehicle in the population has the defect. Another 248 SUVs are covered in Canada.
An unapproved oil
The problem sits in the Integrated Park Module of the HF55 hybrid transmission, a part supplied by EFI Automotive from Wuhan, China. According to Ford's defect report to NHTSA, the supplier switched to a different anti-rust oil without Ford validating it. That oil can eat through the protective coating on the module's circuit board, and the resulting corrosion causes a voltage drop on a rotary sensor. The powertrain software reads the drop as a fault and shifts the transmission into Neutral, even at speed.
The same failure can strike a parked SUV, which may then refuse to shift out of Park. Either way, the warning signs are a lit wrench light plus a "Service Vehicle Soon" or "Shifting System Error" message in the cluster.
How Ford found it
The trail starts outside North America. In July, a regional Ford review group looked into warning lights and SUVs stuck in Park. In August, two warranty claims for loss of drive power on 2026 Ford Edge hybrids pushed the case to Ford's global and then North American teams. Failure analysis in September pinned the corrosion on the oil, and Ford approved the recall on October 13.
By September 28, Ford counted 15 related U.S. warranty claims and 106 worldwide. It says it knows of no crashes, fires, or injuries.
What owners should expect
Dealers were notified October 26, and VINs became searchable on NHTSA's site the same day. Interim letters warning owners of the hazard go out November 2–6. A second letter will follow once parts are available; Ford lists that step only as a "phased recall," with no date. The fix is a new module loaded with the latest software and built without the problem oil. Ford's recall number is 26S75, and its customer line is 1-866-436-7332.
It's not the Nautilus Hybrid's first trip back to the dealer this year. In July, Ford expanded a recall for a missing pedestrian alert sound to 66,383 Nautilus and Explorer hybrids, including vehicles that had already been repaired once.
A hardware swap also costs Ford more than a software patch, which matters as the company tries to cut $1 billion from material and warranty costs this year. Still, 11,623 SUVs is a small campaign by Ford's standards, and a recall count alone says little about how reliable a car is. What owners need now is a date for the parts.
